Benefits of technology
[0006]In accordance with a present embodiment, an indicating lamp device includes a casing comprising a panel defining a plurality of through holes therein. The casing houses a plurality of lamps and a plurality of opaque light shields therein. Each lamp includes a light source and a light pillar extending from the light source into the through holes to transmit light emitted by the light source to an exterior of the casing via the corresponding through hole. The opaque light shields are sleeved around circumferential outer surfaces of the light pillars respectively, for preventing light transmitted in the light pillars from leaking.
Problems solved by technology
When several indicating lamps are close to each other, interference between adjacent lamps may occur.
When one indicating lamp brightens; the adjacent indicating lamps may also seem to brighten, which can be misunderstood by users.

Embodiment Construction
[0011]Embodiments of the present embodiment will now be described in detail below and with reference to the drawings.
[0012]Referring to FIGS. 1-2, an indicating lamp device 100 in accordance with a present embodiment comprises a casing 110, a plurality of lamps 120, a base plate 140, and a plurality of opaque light shields 118. Each lamp 120 comprises a light source 160, and a light pillar 130. The casing 110 is used for housing the lamps 120, the base plate 140, the light shields 118, and other components (not shown) therein. The base plate 140 is secured to the casing 110 and supports the lamps 120 thereon. The light shields 118 are sleeved around the light pillars 130, for preventing light transmitted in the light pillars 130 from leaking out and influencing the appearance of the adjacent lamps 120.
[0013]The casing 110 comprises a panel 112 defining a plurality of through holes 116 therein. The light pillars 130 are disposed between the light sources 160 and the panel 110 to tran...

Description
BACKGROUND[0001]1. Technical Field[0002]The present invention relates to lamps and, particularly, to an indicating lamp device.[0003]2. Description of Related Art[0004]Most apparatuses use indicating lamps to indicate operation state or other information of the apparatuses. When several indicating lamps are close to each other, interference between adjacent lamps may occur. When one indicating lamp brightens; the adjacent indicating lamps may also seem to brighten, which can be misunderstood by users.[0005]What is needed, therefore, is an indicating lamp device which avoids light leakage.SUMMARY [0006]In accordance with a present embodiment, an indicating lamp device includes a casing comprising a panel defining a plurality of through holes therein. The casing houses a plurality of lamps and a plurality of opaque light shields therein. Each lamp includes a light source and a light pillar extending from the light source into the through holes to transmit light emitted by the light so...
